Losing the Analysis Filter Settings

After I do a scan, when I go back to check the Analysis Filter settings (before I run the scan again) they are gone. What am I doing wrong? I assume I should not have to add them again for each scan, right?

Please click the "down" arrow. You will see lots of file extensions are in the list. (Not just the one you mention!)

If you do not want to use file extensions (although the list is extremely comprehensive) there is also a list using MIME types meaning you *can* remove all the file extensions from the list if you wish using the [ - ] button. However, unless you are very sure, I would recommend against it

> Can you please explain how that works?

Based on your questions, I think you should check his page about how the [ + ] [ - ] and drop down lists work in A1SG configuration (basicly, all items in the dropdown list are active/selected)
